Relativity and Cosmology

On the Cold Big Bang Cosmology an Alternative Solution Within the GR Cosmology

We solve the general relativity (GR) field equations under the cosmological scope via one extra postulate. The plausibility of the postulate resides within the Heisenberg indeterminacy principle, being heuristically analysed throughout the appendix. Under this approach, a negative energy density may provide the positive energy content of the universe via fluctuation, since the question of conservation of energy in cosmology is weakened, supported by the known lack of scope of the Noether's theorem in cosmology. The initial condition of the primordial universe turns out to have a natural cutoff such that the temperature of the cosmological substratum converges to the absolute zero, instead of the stablished divergence at the very beginning. The adopted postulate provides an explanation for
the cosmological dark energy open question. The solution agrees with cosmological observations,
including a 2.7K CMBT prediction.
